Dyno Test: Pray Ported OEM vs PP MSD Intake Manifold
The test mule is a 2018 Camaro 2SS 1LE. Basic modifications are a flex fuel sensor, Roto-Fab dry CAI intake, Soler Performance ported 95 MM throttle body, New Era Performance cat delete pipes and a tune. The intake manifolds tested are an OEM intake manifold ported by Pray Performance and an MSD LT1 Airforce intake manifold, also ported by Pray Performance. The car was tuned at Church Automotive( http://churchautotesting.com/ ) with all of the mods listed + the ported OEM intake manifold. On April 23 of this year we took the car to Superior Automotive's Dynojet to see where the car was with the tune-it made 464 HP and 468 torque.
We installed the Pray Ported MSD intake manifold in early June. We took the car to Natural Aspirations( http://www.naturalaspirations.com/ )and dialed in the air/fuel for the new intake manifold. Today we returned to Superior Automotive to compare the results. As you can see by the graph, the Pray Ported OEM intake manifold is slightly better below 5,000 RPM, with a significant advantage right at 4,000 RPM. Above 5,000 RPM the MSD is better, posting a gain in peak HP of about 15 HP, but a whopping 33 HP gain at 6,500 RPM. For reference, we baselined this car bone stock on 91 octane pump gas July 31, 2019 at Superior and it made 403 HP and 404 torque. Is it worth $1500 for 15 peak HP? You decide. Pray did the same test a couple of years back and the results are comparable : https://www.camaro6.com/forums/showthread.php?t=494652

I would say that's a significant difference when shifting at 6600-6700 or so rpms. Stock is done around 5700. Thanks for the post.

I think it's definitely worth it especially considering you're able to get more power in the higher rpms. People are paying the same amount if not more for kooks and American racing headers and x pipe to roughly make the same 15 peak horsepower. If you decide to do heads and cam there's going to be even more power disparity between manifolds.

Sounds like cat delete pipes might be comparable to catted longtubes (the only way I'll do).

Agree with this, try shifting around that rpm zone to get the most out of your improvement. I have an MSD on my SS too, and try to shift in that area.

super easy to port the MSD, that said there is a seam just before the flange to the head. I would like to fill it and smooth it with something? Two part epoxy? JB weld for plastic? dunno. Anybody done it?

perhaps we share a difference of opinion. if one is going to spend the $1k+ on a high performance intake manifold, spending an additional $300? on porting and matching is not only beneficial but also necessary. otherwise, leave the stock stuff on it. i’m not an 85%er. ill do it right or not do it at all.

I used to work with his dad at Harbor City Honda, back in the day. I tuned the car, Chris provided the dyno.
